In a memo to staffers, NBC News chairman Andrew Lack said executives received a detailed complaint about inappropriate sexual behavior in the workplace by Lauer that were a “clear violation” of company standards. “While it is the first complaint about his behavior in the over 20 years he’s been at NBC News, we were also presented with reason to believe this may not have been an isolated incident,” Lack wrote.

Lauer has been on “Today” for over two decades, working alongside anchors including Katie Couric, Meredith Vieira, Ann Curry, and Guthrie.
